Slip-On Flanges are probably the most common type of flanges in the industry and are ideal for lower pressure applications.  You do not have to specify the pipe schedule when using slip-on flanges due to the fact that its inside diameter is determined by the outside diameter of the pipe.  This outside diameter of the pipe does not change for the different schedules.  This often makes these easier to stock for vendors.  Fabricators also like the fact that these flanges are slightly easier to align than weld neck flanges.  They also are slightly easier to cut pipe to the proper length for.  They can be used for high temperature and pressure applications but are not generally recommended as compared to other types of flanges.  ASME B16.5 Code limits their usage in the 1500#-2500# (lbs.) weight classes.

Specialty Flange and Fitting, Inc. offers these flanges in stainless and alloy material. 

Key Features:

• Most commonly stocked flange due to the fact that one size fits all pipe schedules.
• Fabricators can more easily cut pipe to length for slip-on flanges and their smaller thickness allows for easier alignment of bolting holes
• ASME B16.5 code limits their usage for 1500#-2500# (lbs.) applications and they are generally not preferred for high pressure temperature environments.
